 "This push fixes a memory corruption issue in caam, as well as
  reverting the new optimised crct10dif implementation as it breaks boot
  on initrd systems.

  Hopefully crct10dif will be reinstated once the supporting code is
  added so that it doesn't break boot"

Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.

Jussi Kivilinna 99f42f937a Revert "crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher"
This reverts commit cf1521a1a5.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX
implementation is therefore faster and this implementation should be removed.

Converting this implementation to use the same method as in twofish/AVX for
table look-ups would give additional ~3% speed up vs twofish/AVX, but would
hardly be worth of the added code and binary size.

Jussi Kivilinna fe6510b5d6 crypto: aesni_intel - fix accessing of unaligned memory
The new XTS code for aesni_intel uses input buffers directly as memory operands
for pxor instructions, which causes crash if those buffers are not aligned to
16 bytes.

Patch changes XTS code to handle unaligned memory correctly, by loading memory
with movdqu instead.

Jan Beulich 2baad6121e x86, crc32-pclmul: Fix build with older binutils
binutils prior to 2.18 (e.g. the ones found on SLE10) don't support
assembling PEXTRD, so a macro based approach like the one for PCLMULQDQ
in the same file should be used.

This requires making the helper macros capable of recognizing 32-bit
general purpose register operands.

Jussi Kivilinna de614e561b crypto: sha256_ssse3 - fix stack corruption with SSSE3 and AVX implementations
The _XFER stack element size was set too small, 8 bytes, when it needs to be
16 bytes. As _XFER is the last stack element used by these implementations,
the 16 byte stores with 'movdqa' corrupt the stack where the value of register
%r12 is temporarily stored. As these implementations align the stack pointer
to 16 bytes, this corruption did not happen every time.

Patch corrects this issue.

Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring
32 parallel blocks for input (512 bytes). Compared to AVX implementation, this
version is extended to use the 256-bit wide YMM registers. For AES-NI
instructions data is split to two 128-bit registers and merged afterwards.
Even with this additional handling, performance should be higher compared
to the AES-NI/AVX implementation.

I chose not to optimize smaller than block size of 256 bytes, since XTS is

performance is reduced in tcrypt for 64 byte long blocks.

Jussi Kivilinna 873b9cafa8 crypto: x86 - build AVX block cipher implementations only if assembler supports AVX instructions
These modules require AVX support in assembler, so add new check to Makefile
for this.

Other option would be to use CONFIG_AS_AVX inside source files, but that would
result dummy/empty/no-fuctionality modules being created.
